Hi,
Just to provide an update here, I have now verified that the problem is
specifically with Open Babel version 2.4.1.
After uninstalling OpenBabel and Pybel on the same machine, I was able to
successfully install Open Babel 2.3.2 [ttp://
sourceforge.net/projects/openbabel/files/openbabel/2.3.2/OpenBabel2.3.2a_Windows_Installer.exe/download]
and then Pybel 1.8, using the same installer I mentioned previously.
[With regard to the need to elevate privileges with a separate ADMIN
account, this did require me to manually update my SYSTEM path, locate
C:\User\[ADMIN]\AppData\Roaming\OpenBabel-[version], move this to
C:\User\[LOGIN ACCOUNT]\AppData\Roaming\OpenBabel-[version] and set a
SYSTEM variable BABEL_DATADIR=C:\User\[LOGIN
ACCOUNT]\AppData\Roaming\OpenBabel-[version]\data. This enabled use of
obabel in a new [LOGIN ACCOUNT] command prompt but still generated the same
import pybel error as before. So, although this is an added complication,
it does not appear to be related to the problem importing pybel with
OpenBabel-2.4.1 that I previously reported.]
I checked the software was correctly installed and working as expected as
follows:
